Title: Breather device for irregular ground running vehicle
Inventor: YAMADA KOZO
IPC: F16H57/027
Filed: 1989-06-02
Abstract: PURPOSE:To prevent damage in a sealed part or the like due to a change of internal pressure in a case by connecting one end of a breather pipe to communicate with the inside of the closed case and the other end to communicate with the inside of a closed air chamber whose internal capacity is variable in accordance with a pressure. CONSTITUTION:An air chamber 31 is formed in a bellows shape further in a closed condition in a manner, wherein an internal capacity is changed by a difference between internal and external pressures, and provided with an opening 32 to which a breather pipe 30 is mounted. An irregular ground-running vehicle runs to repeat acceleration and deceleration, even when a temperature in a closed drum brake 20 is increased with air expanded, the internal capacity of the air chamber 31, which communicates by the breather pipe 30, is increased in accordance with the air expanded. While even in the case of the closed drum brake 20 cooled by water when the vehicle runs across a marshy place and/or a river, the internal capacity of the air chamber 31 is contracted. Accordingly, a change of pressure in the closed drum brake 20 is prevented, and water is prevented from infiltrating due to damage in a sealed part 23.

Title: Controlling method for spindle motor
Inventor: WATANABE YUSUKE
IPC: H02P6/24
Filed: 1989-06-02
Abstract: PURPOSE:To stop a spindle motor in a short time by reversing a driving current at the time of stopping said spindle motor, by operating the time and number of revolutions until the cut-off of the rotational speed and acceleration of said motor and by shutting OFF a reverse current, when operated values are smaller than specified ones. CONSTITUTION:A controller 1 performs the drive control of a spindle motor 2 to control the stop and forward and reverse rotations of said motor in conjunction with a system part not shown, e.g. a disc storage medium. For that purpose, said controller outputs a duty control signal DD corresponding to the driving current of said motor 2 to output a signal DR expressing the direction of rotation of said motor 2. A rotation angle sensor 6 outputs a pulse PR corresponding to a rotational speed and a pulse interval measuring part 7 measures the rotating state of said motor 2. When said motor 2 is to be stopped, the controller 1 flows a current directed oppositely to the current flowing until that time. When the number of revolutions or acceleration of the motor 2 falls below a specified value by the output of the measuring part 7, a reverse current is shut OFF. Thus, it is possible to shorten the period of time required for stopping said motor.
